TWO:A new career came to open itself to me. And one must have been either without address or buried in stupidity not to have profited by an opportunity so advantageous. I seized this unexpected opportunity by the forelock. By dint of negotiating and intriguing, I succeeded in indemnifying our monarchy for its past losses by incorporating Polish Prussia with my old provinces. This acquisition was one of the most important we could make, because it joined Pommern to East Prussia, and because, rendering us masters of the Weichsel River, we gained the double advantage of being able to defend that kingdom (East Prussia), and to draw considerable tolls from the Weichsel, as all the trade of Poland goes by that river.DORIS RITTERS PUNISHMENT.

Membrane separation type solvent dehydration system

Great attention is recently being paid to global environmental issues, and it is now conceivable that companies will need to treat used solvents themselves. In consideration of this kind of social issue, we have developed a “membrane separation type solvent dehydration system,” which uses a polyimide membrane with superior dehydration properties developed by Ube Industries, Ltd. in combination with our own distillation and concentration technology that has resulted in solvents being more easily recovered.

THREE:I am authorized to offer your majesty two million guilders [,000,000] if your majesty will consent to relinquish this enterprise and retire from Silesia.
  • 1Under the distillation system, even in case of azeotropic solvent compositions, this system which remove water vapor by the polyimide membrane will easily dehydrate.
  • 2In comparison with the distillation system, it significantly saves on use of steam.
  • 3Dehydration can be performed through merely supplying evaporated vapor to the membrane module and maintaining the differential pressure between the permeable side and the impermeable side.
  • 4Solvent purity of 99.9% or more can be achieved by carrying out dehydration with a polyimide membrane only.
  • 5The polyimide membrane has superior heat and solvent resistance. Therefore, the vapor permeation system reduces contamination of the membrane and thus extends its life.
THREE:I shall be in the front and in the rear of the army. I shall fly from one wing to the other. No squadron and no company will escape my observation. Those who act well I will reward, and will never forget them. We shall soon either have beaten the enemy or we shall see each other no more.FREDERICK AND HIS DOGS.

The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:The king paused. A general murmur of applause indicated the united resolve to conquer or to die. Frederick immediately added:
  • 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
  • 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
THREE:

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
